Leaf at Assiniboine Park in Winnipeg by KPMB and Architecture49

The Leaf is Winnipeg’s latest botanical conservatory at Assiniboine Park. It represents a bold fusion of architecture and horticulture designed to engage the public with living plant life in a modern, urban context.

Completed in 2022, this 84,400-square-foot facility was designed by KPMB Architects in collaboration with Architecture49. It stands as a horticultural sanctuary for the 21st century, celebrating Canada’s cultural diversity and inviting people of all ages to connect with the natural world.

Its LEED Gold certification highlights a strong commitment to sustainability and responsible design within a civic landmark.

Design and Collaboration: A modern conservatory at the intersection of architecture and horticulture

Designed by KPMB Architects with Architecture49, The Leaf is more than a glasshouse. It is an integrated public space where architectural form and plant science work together.

The project’s 84,400 ft² scale was chosen to host dynamic botanical displays and education spaces. Visitor programming is included without sacrificing human-scale interaction with nature.

The Leaf aims to be a welcoming civic space that anchors Assiniboine Park as a living laboratory for urban ecology.

Architectural Vision and Spatial Experience

The Leaf uses transparent envelope strategies and carefully shaped volumes to frame botanical experiences. Its design emphasizes daylight and visual connections to outdoor landscapes.

Indoor microclimates showcase diverse plant life in immersive, educational settings. By blending contemporary architecture with horticultural expertise, the project creates a visually compelling and scientifically rich public realm.

Visitors are invited to observe, learn, and participate in the life of a living conservatory.

Sustainability and Certification

The building’s LEED Gold certification reflects sustainability strategies such as energy-efficient systems and water stewardship. Responsible materials are used throughout the facility.

The Leaf balances high-performance environmental targets with memorable visitor experiences. The project uses daylighting, integrated climate considerations, and a modular horticultural program to support diverse plant communities while minimizing environmental impact.

Education, Community, and Public Engagement

The Leaf serves as a catalyst for changing how Winnipeg and beyond perceive and interact with nature. Its programming prioritizes education and outreach, aiming to captivate new generations with immersive botanical experiences and hands-on learning.

By combining exhibition spaces with educational initiatives, the conservatory seeks to deepen appreciation for plant life among residents and visitors.

Educational Programming and Botanical Literacy

Programming at The Leaf focuses on plant ecology, conservation, and sustainable practices. The facility functions as a living classroom, offering tours, workshops, and partnerships with schools and community groups.

The emphasis is on practical knowledge—how plants adapt, how ecosystems function, and how urban residents can contribute to a more sustainable future.

Public Space, Accessibility, and Lighting

The Leaf’s public realm is inclusive and accessible, reinforcing that nature is a shared urban resource. The lighting design, by Mulvey & Banani Lighting Inc., enhances the beauty of plant displays and supports energy efficiency.

Thoughtful illumination and a welcoming atmosphere make the conservatory a versatile venue for education, cultural programming, and community events.
